UNITED STATES PATENT OFFICEO IMPROVEMENT IN MOWING-MACHIINES.

Specification forming part 0f Letters Patent N0. 55,654, dated June 19, 1866.

To all whom t may concern:

Be it known that we, ELEAZER HINCHLEY and DAVID' HINGHLEY, both ot' the city and county of Worcester and State of Massachusetts,have invented a new and useful Improvement in lllowiug-lllachines; and we do hereby declare the same to be fully described in the followingspecification,and represented in the accompanyingdrawings, ot' which- Figure l is a top View, and Fig. il a longitudinal and vertical section, ot' a mowing-inachneprovided with our invention,the said section heilig' laken through the canrwheel to be hereinafter described.

One great object we have had in view in making' our improvement has been to obtain a very simple and eectual mechanism for operating the knife by means of the driving'- wheel ot' the machine. This we accomplish by a peculiar cam-wheel-that is, one having an uneven number ot' cams-and by a rockerlever and a connecting-rod, a beveled pinion and annulus,arranged and combined with the driving-wheel and the knife, as hereinafter eX- plained.

In the said drawings, A denotes the trame ot' the machine, and B its toothed knife-bar, the latter being so hinged to the frame as to be capable ot' being turned from a horizontal position up into or about into a vertical one. U is the serrated knife or cutter, which is applied to the knife-bar, and is constructed so as to operate therewith in the ordinary manner.

A coi'inecting-rod, D, hinged to the knife, leads and is jointed to the longer arm of a rocker-lever, lil, which supports the journals ot' the friction-rollers a and has its fulcrum c sustained by the frame A. The journals ef of the friction-rollers are arranged on opposite sides of the fulcrum of the lever-that is, one journal is extended from one arm ot' the lever and the other journal is projected from the other arm ot' such lever, each journal being at an equal distance from the fulcrum.

A cam-Wheel, F, shaped as shown in the drawingsthat is, having a series of odd number of cams, g g g, projecting` from its periphery-operates with the frictionrollers ot' the rocke1'lever-that is, so as on being revolved to strike them alternately and producea quick Vibratory movement ot the said rocker-lever, such as will cause it to impart to the knife its` necessary longitudinal movements in the knife. bar in order to enable such knife to cnt grass when interposed between the teeth of such bar. rlhe said cam-wheel F is tiXed to a short shaft, G, dulysupport-edin boxes It li, and being provided with a bevel-pinion, H, to work into a beveled-toothed annulus, l, arranged within and making part ot' a wheel, K, in manner as represented in the drawings, the periphery ot' the rim t' ot' the wheel K being' provided with teeth la 7c, to enable it to take hold ot' or adhere to the ground. The said wheel K is fixed to an axle, L, on which is another wheel, M, that revolves t'reely on the axle,and, with the wheel K, serves to support the niachineon the ground.

A handle, pole, or shat't, may beattixed to the frame A, to enable the machine to be drawn over the surface ot' a piece of land either by manual or animal power.

The machine made as above described is very simple in construction, and has been de-4 signed specially as a hand machine for mowing lawns.

We claim- The combination and arrangement of the cam-wheel F, rocker-lever E, connecting-rod D, the shaft G, and its beveled pinion H and annulus l, with the driving-wheel K, and the knife C, the said rocker-lever being provided with friction-rollers or project-ions for the cam- Wheel to operate against, and the whole being' substantially as specified, and for the purpose ot' operating the knife G by the revolution ot' the wheel K.
